Q

What’s the function of the cell wall

A

It maintains the cell structure and supports the cell

18
Q

Is cell wall only in the animal cell if not what cell

A

No it is in the plant cell

19
Q

Is chlorophyll in the cytoplasm if it isn’t what part of the cell contains chlorophyll

A

Its is the chloroplast

20
Q

Does chloroplast contain a blue or green pigment and what is it called

A

Green chlorophyll

21
Q

What is the function of chloroplast in a plant cell

A

The site of photosynthesis

22
Q

Is chloroplasts in both cells if not what cell

A

Not both only plant cells

23
Q

What is the Vacuole and what does if contain

A

A fluid filled sac which contains cell sap

24
Q

Is the vacuole in both animal and plant cells if not the what cell

A

Not both just plant cells

25
Q

What is the function of the vacuole

A

Contains cell sap

26
Q

Is the valcuole in both animal and plant cells if not what cell

A

Not both just plant cells

27
Q

What is the function of the vacuole

A

Contain cell sap

28
Q

How do we view cells

A

Micro scope

29
Q

What is the sum for total magnification

A

Total magnification = Eye piece x objective

30
Q

How do you prepare on onion side ( in steps ) ( plant cell)

A
  1. Perpare a 🔥small thin piece🔥 of 🔥onion🔥 and place it on the 🔥slide 🔥( onion skin should 🔥not🔥 be 🔥folded🔥 )
  2. Put one drop of 🔥iodine🔥 on the 🔥slide 🔥
  3. 🔥Gently🔥 put a 🔥cover slip over the cells🔥 using a 🔥mounted needle don’t make air bubbles🔥
  4. 🔥View🔥 the side under the 🔥microscope🔥 and draw what you can 🔥see 🔥
31
Q

What does the iodine help us to do when preparing a plant cell slide

A

Helps us see that plant cell better

32
Q

What is the lower magnification

A

4x

33
Q

Is it the same when preparing a plant cell compared to a animal cell ( Yes or No )

A

No

34
Q

How do you prepare a cheek slide ( in steps ) ( animal cell)

A
  1. Scrub the inside of your cheek with a cotton bud, smear it onto the centre of the slide
  2. Put one drop of methyl blue on the slide
  3. Gently put a cover slip over the cell
  4. View the slide under the microscope and draw what you can see
35
Q

What chemical helps you see animal cells better

A

Methyl blue

36
Q

Description words for onion cells

A

Shaped like a brick wall
Structured and in Order

37
Q

Description words for cheek cell

A

No particular shape cells overlap and can fall over

38
Q

Label the animal cell on notes

A
39
Q

Label plant cell on notes

A
40
Q

Steps for mitosis GOOO‼️ important

A
  1. DNA in the nucleus coils into single stranded chromosomes ( visible in nucleus)
  2. The single stranded chromosomes replicate In preparation for cell devision

3.chromosomes ( pairs of chromatids) line up along the equator of the cell

  1. Spindle fivers form attaching to the centromere. As these contract they pull the chromatids apart towards opposite ends of the cells.
  2. Nuclear membrane reforms around both sets of chromosomes
  3. Cytoplasm spilts producing two identical daughter cells
